Air Carbon Arc Gouging

Basics

• A Method of Cutting Thick Metal
• Uses a Hollow Graphite Rod that Compressed Air is blown through while an arc is created in a similar manner to Shielded Metal Arc Welding
• This melts, oxidizes and blows away metal rapidly
• Very Loud (Above most Noise Exposure Limits?) and also can launch the molten metal long distances which presents another safety hazard
